One. Scope: BK control transformer is suitable for 500V 50-60Hz voltage to the circuit, it is often used as a tool to control lights and appliances or partial indicator of power use. BK control transformer shell structure can be divided according to type, according to the installation can be divided into vertical. Three. Working conditions and installation conditions: 1. Install location not more than 2000 meters above sea level; 2. atmospheric relative humidity in the ambient air + 40 ℃ humidity less than 50% at lower temperatures can have a higher relative humidity, the wettest monthly average maximum humidity of 90%, while the monthly average minimum temperature of + 25 ℃, and taking into account the temperature change in the condensation product surface. 3. 4. place from rain and snow medium does not enough to corrode metal and damage the insulation of gas and conductive dust, should be installed in no shaking shock vibration. Order control transformer Note ☆ before buying, a good first estimate of the total electrical capacity you use, and with the same margin of transformers, transformer sure not to burn the instantaneous start before ☆ installation, you should carefully check the data listed in the nameplate if it meets your requirements, confirmation, before installation. ☆ power work, the transformer core and coil heat, (but the temperature does not exceed 80 ° C) is a normal phenomenon, if the heating, beyond 80 ° C, even smoke, you should cut off the power switch, re-check the electrical capacity you are using. ☆ special transformers according to customer requirements and should provide the input voltage and output voltage. How many watts of output voltage of each power distribution control transformer ordering and delivery ☆ Order: Make sure a good product models, specifications, voltage, so as not to waste your valuable time. ☆ Shipping: control transformers due to heavier default Logistics, freight collect. Powerware Powerware sale protection electrical control electrical transformer products sold since production date within 12 months (to sell time), at the customer normal storage, maintenance, use conditions, due to product quality problems can not be During normal use, Powerware promised to provide "Three Guarantees" service. For the following situations, providing paid services: ☆ unauthorized disassemble the product caused by the failure. ☆ because of poor working conditions and improper operation or user power system line problems caused by the failure or overload. ☆ damage caused by natural disasters. ☆ more than "three guarantees" service life of the product.
